Question

find the mean, (\bar{x}), of the data.

251, 224, 237, 255, 268

(\bar{x} = )

Explanation:

Step1: Calculate the sum of data

$$251 + 224+237 + 255+268=1235$$

Step2: Calculate the number of data

There are \(n = 5\) data points.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), so \(\bar{x}=\frac{1235}{5}=247\)

Answer:

\(247\)
